Ｈ形鋼部材の複合座屈要素の提案および空間構造の線形座屈解析への応用

The present study presents a new FEM element for buckling analysis of members H-section and its application to spatial structures. is fundamentally composed three parallel beams together with two struts normal the elements, enabling consideration flexural-torsional buckling. study, first, performs static under torsional moments. Second, subjected axial forces, followed by lateral bending moments at both ends. Through comparison results solutions based on differential equations, validates proposed element. Third, extends analyses structures which represent fundamental structural characteristics structures, also considering effect stiffening added Finally, discussions, authors prove effectiveness in case where adopted are subject
